fix(ci): update vercel-action to main branch (#1533)

## Summary
- Updates `amondnet/vercel-action` from pinned `v41.1.4` to `main`
branch in both deploy workflows
- The pin was originally due to v42 failing with "Error: Provided path
./ is not absolute", which is resolved in this PR
- Deployments now use API
